Plastic parts should be designed with draft to prevent sticking and ejector pin push marks on the outward surface during ejection. Applying the proper draft angles or tapers on the surface of an injection molded part is critical to part moldability.
Overmolding is a process where a single part is created using two or more different materials in combination. The first material, often referred to as …
Medical and scientific devices pose three key challenges for companies like Celling Biosciences: time, quality, and cost. On one hand, to build a reputation for …
There are many elements that influence the plastic injection molding manufacturing process. A key component to this process is the material used to create the part itself. There are numerous thermoplastic resin material options that are available for plastic injection molded parts. The content of these materials will directly affect part production. It will impact several critical factors in the manufacturing process such as strength, durability, cost of production and time to market.
Complex insert molding is sometimes utilized in order to get parts to market faster. It is a process in which plastic is injected into a mold that contains a pre-placed insert. The result of insert molding is a single molded plastic piece with an insert surrounded by the plastic.
The success of your plastic part relies upon many key elements working simultaneously. There are many factors that influence the outcome of your plastic part and should be taken into consideration when designing with plastics as follows:
Designing your part for the plastic injection molding process can sometimes be a challenge. Refer to our quick reference guide below featuring some best practices …
Plastic resin pellets are loaded into the hopper, where it travels into the barrel of the injection molding machine. Through both heat and pressure, the plastic pellets are melted into a molten material that is ready to be injected. As the screw turns it creates pressure which will help push the molten plastic through the nozzle and into the mold.
Before we jump into the injection molding pitfalls you should avoid, here’s a quick review of the Injection Molding Process, Injection Molding Basics, and Rapid Injection Molding.
